The article mentions Apple still hasn't moved over iTunes (store, movie, music, Match) or Radio service traffic, among other things (those are still on Akamai/Level3). I'm sure Apple's planning on moving at least some of these services over to their new CDN.

A CDN like this would be really helpful for that streaming service they're probably working on.

Which streaming service? They bought one this year along with really expensive headphones.

I was being general, but yes, I'm going to go ahead and say their acquisition of Beats may be a leading cause of Apple upping their CDN power, but who knows.

iTunes Match is fast for me. And alot was stuff it didn't match and uploaded from me (which is odd because they sell some of it now. I bought the classical music direct).

I can download and play at work almost instantaneously.

uploading this to match was not fun.. http://www.deutschegrammophon.com/en/cat/4778167

If you are big enough, at some point it doesn't make sense to pay people to be your CDN.

True. This has to do more with knowing and understanding (and being able to control) your traffic and content patterns rather than simply being big. When part of your business is making recommendations to people on what they should watch (listen to) next, content propagation and pre-caching is a no-brainer.

Expect a NetFlix competitor, and a TV competitor.

...then expect Netflix-like problems with big ISPs?

That's my thought too.

iTunes?
